Determine the slope and the y-intercept

B m = 1/2 y-int = -1

Step-by-step explanation:

at x = 0, y=-1 so that is the y-intercept

to find the slope, use the slope formula m=(y2-y1)/(x2-x1)

m=(0--1)/(2-0)

m=1/2

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :
